Multi-wavelength modeling of the spatially resolved debris disk of HD 107146
Aims. We aim to constrain the location, composition, and dynamical state of planetesimal populations and dust around the young, sun-like (G2 V) star HD 107146. Methods. We consider coronagraphic observations obtained with the Advanced Camera for Surveys (HST/ACS) onboard the HST in broad V (λc ≈ 0.6 μm) and broad I (λc ≈ 0.8 μm) filters, a resolved 1.3 mm map obtained with the Combined Array fo...
متن کاملResolved debris disk emission around η Tel : a young Solar System or ongoing planet formation ?
Aims. 60% of the A star members of the 12 Myr old β Pictoris moving group (BPMG) show significant excess emission in the mid-infrared, several million years after the proto-planetary disk is thought to disperse. Theoretical models suggest this peak may coincide with the formation of Pluto-sized planetesimals in the disk, stirring smaller bodies into collisional destruction. Here we present reso...

15 صفحه اولDiscovery of Resolved Debris Disk around Hd 131835
We report the discovery of the resolved disk around HD 131835 and present the analysis and modeling of its thermal emission. HD 131835 is a ∼15 Myr A2 star in the Scorpius–Centaurus OB association at a distance of 122.7+ 12.8 16.2 pc . The extended disk has been detected to ~ 1. 5 (200 AU) at 11.7 and 18.3 μm with T-ReCS on Gemini South. The disk is inclined at an angle of ∼75°with the positi...
متن کاملModels of the Η Corvi Debris Disk from the Keck Interferometer, Spitzer, and Herschel
Debris disks are signposts of analogs to small-body populations of the solar system, often, however, with much higher masses and dust production rates. The disk associated with the nearby star η Crv is especially striking, as it shows strong midand far-infrared excesses despite an age of ∼1.4 Gyr. We undertake constructing a consistent model of the system that can explain a diverse collection o...
